Enum RestartReason 

pub enum RestartReason {
    UserRequested,
    CleanShutdown,
    ErrorExit(i32),
    Segfault,
    Killed,
    Aborted,
    Terminated,
    SignalOther(i32),
    Unknown,
}

Categorized reasons for subprocess restart.

Determined from the subprocess exit status, distinguishing between clean exits, error exits, and signal-based terminations.

Detection Methods

Variant	Detection
UserRequested	Explicit restart command
CleanShutdown	exit(0)
ErrorExit(n)	exit(n) where n ≠ 0
Segfault	SIGSEGV (signal 11)
Killed	SIGKILL (signal 9), possibly OOM
Aborted	SIGABRT (signal 6)
Terminated	SIGTERM (signal 15)
SignalOther(n)	Other signal
Unknown	No exit code or signal available

Variants

UserRequested

User explicitly requested restart via command

CleanShutdown

Clean shutdown with exit code 0

ErrorExit(i32)

Error exit with non-zero code

Segfault

Segmentation fault (SIGSEGV, signal 11)

Killed

Killed (SIGKILL, signal 9) - possibly OOM

Aborted

Aborted (SIGABRT, signal 6) - typically assertion failure

Terminated

Terminated (SIGTERM, signal 15) - graceful shutdown request

SignalOther(i32)

Other signal termination

Unknown

Unknown reason (no exit code or signal)

Implementations

impl RestartReason

pub fn from_exit_status(status: ExitStatus) -> Self

Determine restart reason from process exit status.

On Unix, checks for signal termination first, then exit code. On other platforms, only exit code is available.

Example

use std::process::Command;
use oxur_repl::metrics::RestartReason;

let mut child = Command::new("ls").spawn().unwrap();
let status = child.wait().unwrap();
let reason = RestartReason::from_exit_status(status);

pub fn as_label(&self) -> &'static str

Get the metrics label for this restart reason.

Returns a static string suitable for use as a metrics label value.

pub fn is_signal(&self) -> bool

Check if this is a signal-based termination.

pub fn is_clean(&self) -> bool

Check if this is a clean shutdown.

Trait Implementations

impl Clone for RestartReason

fn clone(&self) -> RestartReason

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RestartReason

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RestartReason

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for RestartReason

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for RestartReason

fn eq(&self, other: &RestartReason) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RestartReason

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
